Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a packaging box and packaging components. Background Technology

[0002] During product transportation, packaging boxes are often used to protect the products. Some products have connecting wire harnesses. Since the product body and the connecting wire harness are generally quite different in size, the packaging box cannot protect both the product body and the connecting wire harness at the same time, or a more complex structure is required. Utility Model Content

[0003] Therefore, this utility model provides a packaging box and packaging assembly that, while possessing a relatively simple structure, also ensures protection for the product body and connecting wiring harness. The technical solution is as follows:

[0004] In a first aspect, a packaging box is provided, the packaging box comprising: a box body and a cushioning liner, wherein the cushioning liner and the box body are formed by folding an integrally molded sheet material through preset creases;

[0005] The box body includes opposing first and second side walls;

[0006] The cushioning liner is located inside the box and abuts against the first side wall, with a gap between the cushioning liner and the second side wall to form a limiting area.

[0007] The limiting area formed between the cushioning liner and the second sidewall has a small space, which can protect the connecting wire harness located inside the box, while the remaining space inside the box is larger, which can protect the product itself.

[0008] In some possible implementations, the cushioning liner is located at one end of the housing along a first direction;

[0009] The buffer liner includes a connecting section, a limiting section, and a supporting section. The connecting section is connected to the first sidewall, the limiting section is connected to the connecting section, and the supporting section is connected to the limiting section.

[0010] The crease between the connecting segment and the first sidewall, as well as the crease between the limiting segment and the connecting segment and the supporting segment, are all parallel to the first direction.

[0011] Since the limiting area is located at one end of the box along the first direction, all the space at the other end of the box can be used to place the product body, thereby improving the space utilization rate inside the box.

[0012] In some possible implementations, the box body also includes a bottom wall;

[0013] The creases between the bottom wall and the first and second side walls are all parallel to the first direction;

[0014] The support section is attached to the bottom wall, and the free end of the support section abuts against the first side wall, so that a limiting area is formed between the limiting section and the second side wall.

[0015] In some possible implementations, the limiting segment is parallel to the second sidewall and perpendicular to the supporting segment.

[0016] The cavity structure formed between the buffer liner and the first sidewall is relatively stable and can provide a limit for the connecting wire harness, which helps to prevent the connecting wire harness from shaking in the limit area, thereby reducing the possible wear marks on the connecting wire harness.

[0017] In some possible implementations, the housing also includes two third sidewalls;

[0018] The two third sidewalls are located at the two ends of the bottom wall along the first direction, and the creases between the bottom wall and the two third sidewalls are parallel to each other and perpendicular to the first direction.

[0019] The bottom wall, the first side wall, the second side wall, and the two third side walls form the box body.

[0020] One third sidewall, together with the cushioning liner, can define the position of the product body in the first direction, and another third sidewall, together with the product body, can define the position of the connecting harness in the first direction.

[0021] In some possible implementations, the packaging box further includes two fastening components, each located at one end of the bottom wall along the first direction;

[0022] The fastening assembly includes a damping plate and two limiting plates;

[0023] The damping plate is located inside the third sidewall at one end and abuts against the first sidewall and the second sidewall along the second direction. The damping plate is connected to the end of the corresponding third sidewall away from the bottom wall along the third direction.

[0024] Both limiting plates are located between the corresponding damping plate and the third sidewall, and are respectively connected to the first sidewall and the second sidewall;

[0025] The crease between the bottom wall and the third side wall extends along the second direction, and the third direction is perpendicular to both the first and second directions.

[0026] The box structure is stable enough, and the fastening components can assist the corresponding third sidewalls for support, improving the structural stability of the box and providing good protection for the product.

[0027] In some possible implementations, the housing further includes a cover and an extension plate;

[0028] The crease between the cover plate and the second sidewall extends along the first direction, and the cover plate is opposite to the bottom wall;

[0029] The extension plate is located outside the first sidewall and is connected to the cover plate. Both ends of the extension plate along the first direction are provided with insert plates, which can be inserted between the limiting plate and the third sidewall at the corresponding end.

[0030] The cover plate, together with the bottom wall, the first side wall, the second side wall, and the two third side walls, can form a box, thereby limiting the position of the product in three-dimensional space and providing full protection for the product.

[0031] In some possible implementations, the damping plate has a groove on the side facing the bottom wall in the third direction.

[0032] Therefore, the damping plate can be easily unfolded by fastening the groove.

[0033] In some possible implementations, at least one of the third sidewalls has a socket in the middle, the socket penetrating the third sidewall along the first direction.

[0034] Therefore, the packaging box can be easily lifted or picked up by inserting a finger into the socket.

[0035] In some possible implementations, when the packaging box further includes two fastening components, and the fastening components include damping plates, the damping plate at one end is also provided with a clearance hole, the clearance hole being coaxial with the insertion hole.

[0036] This prevents the damping plate from clogging the socket.

[0037] In a second aspect, a packaging assembly is provided, the packaging assembly comprising a packaging box as described in any of the first aspects.

[0038] The packaging component of this embodiment includes the packaging box of this application and has all the beneficial technical effects of any embodiment of this utility model.

[0039] In some possible implementations, the box body also includes a bottom wall;

[0040] The creases between the bottom wall and the first and second side walls are all parallel to the first direction;

[0041] The packaging assembly also includes a cushioning base, the dimensions of which along the first and second directions match the internal dimensions of the box body and are located on the side of the cushioning liner facing away from the bottom wall;

[0042] Both the first direction and the second direction are parallel to the bottom wall, and the first direction and the second direction are perpendicular to each other.

[0043] The cushioning pad can cushion the product in directions perpendicular to the first and second directions.

[0044] In some possible implementations, the cushioning pad is formed by folding a one-piece molded sheet through preset creases, and the cushioning pad includes: a cushioning plate, two first support plates and two second support plates;

[0045] The two first support plates and the two second support plates are all located between the buffer plate and the bottom wall;

[0046] The two first support plates are respectively located at both ends of the buffer plate along the first direction;

[0047] The two second support plates are located at both ends of the buffer plate along the second direction.

[0048] A cavity can be formed between the cushioning pad and the bottom wall, which improves the cushioning capacity of the cushioning pad.

[0049] In some possible implementations, the box body also includes a bottom wall;

[0050] The creases between the bottom wall and the first and second side walls are all parallel to the first direction;

[0051] The buffer liner is located at the first end of the box body along the first direction;

[0052] The packaging assembly also includes a cushioning side liner located at a second end of the cushioning inner liner along the first direction.

[0053] Buffer side liner can improve the protective support of the packaging component for the product along the first direction and improve the structural stability under extreme transportation conditions.

[0054] In some possible implementations, the cushioning side liner is formed by folding a one-piece molded sheet through preset creases, and the cushioning side liner includes: a side limiting plate and two side support plates;

[0055] The side limiting plate is located at the first end of the two side support plates along the first direction, and the crease between the side limiting plate and the support plates of the two side support plates extends along the second direction;

[0056] The side support plate is provided with a third support plate at both ends along the second direction, and the third support plate is located between the two side support plates.

[0057] Both the first direction and the second direction are parallel to the bottom wall, and the first direction and the second direction are perpendicular to each other.

[0058] The interior of the buffer side liner can form a cavity, and the side limiting plate can achieve good cushioning of the product along the first direction 001. At the same time, the structure of the buffer side liner is relatively simple and easy to manufacture, thus significantly reducing labor costs and manufacturing costs. Attached Figure Description

[0079] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0080] This embodiment relates to a packaging box, see reference. Figure 1 As shown, the packaging box includes a box body 1 and a cushioning liner 2. (Referring to...) Figure 14 As shown, the cushioning liner 2 and the box body are made of a single piece of molded sheet material folded along pre-set creases, which makes the structure of the packaging box relatively simple.

[0081] Continue to refer to Figure 1 As shown, the box body 1 includes a first sidewall 111 and a second sidewall 112. (Referring to...) Figure 1 and Figure 2 As shown, the buffer liner 2 is located inside the box 1 and abuts against the first side wall 111. There is a gap between the buffer liner 2 and the second side wall 112 to form a limiting area 3.

[0082] As described above, the structure of the packaging box can be relatively simple. Meanwhile, the limiting area 3 formed between the cushioning liner 2 and the second side wall 112 has a small space, which can protect the connecting wire harness located inside the box body 1, while the remaining space inside the box body 1 is larger, which can protect the product itself. The product can be a charger, adapter, or power adapter, etc.

[0083] In some possible implementations, refer to Figure 3 As shown, the buffer liner 2 is located at one end of the box body 1 along the first direction 001.

[0084] Furthermore, refer to Figure 2 As shown, the buffer liner 2 includes a connecting section 21, a limiting section 22, and a supporting section 23. The connecting section 21 is connected to the first sidewall 111, the limiting section 22 is connected to the connecting section 21, and the supporting section 23 is connected to the limiting section 22.

[0085] Among them, combined Figure 1 As shown, the crease between the connecting segment 21 and the first sidewall 111, as well as the crease between the limiting segment 22 and the connecting segment 21 and the supporting segment 23, are all parallel to the first direction 001.

[0086] Thus, the limiting area 3 formed between the buffer liner 2 and the first sidewall 111 can be located at one end of the housing 1 along the first direction 001. For example, in Figure 1 In this case, the buffer liner 2 can be located inside the box body 1 along the first direction 001 near the right end, and the limiting area 3 can also be located inside the box body 1 along the first direction 001 near the right end. However, the buffer liner 2 can also be located inside the box body 1 along the first direction 001 near the left end, and in this case, the limiting area 3 can also be located inside the box body 1 along the first direction 001 near the right end.

[0087] Since the limiting area 3 is located at one end of the box body 1 along the first direction 001, all the space at the other end of the box body 1 can be used to place the product body, thereby improving the space utilization rate inside the box body 1.

[0088] In some possible implementations, refer to Figure 3 As shown, the box body 1 also includes a bottom wall 113. The creases between the bottom wall 113 and the first side wall 111 and the second side wall 112 are all parallel to the first direction 001.

[0089] refer to Figure 2 As shown, the support section 23 is fitted to the bottom wall 113. For example, in Figure 2 In this structure, the support section 23 can be directly attached to the bottom wall 113, but the support section 23 can also be indirectly attached to the bottom wall 113 through other structures. Furthermore, the free end of the support section 23 abuts against the first side wall 111, thereby forming a limiting area 3 between the limiting section 22 and the second side wall 112.

[0090] For example Figure 2 The example shown is where the support section 23 is directly attached to the bottom wall 113. The limiting section 22, together with the second side wall 112 and the bottom wall 113, forms a limiting area 3 to accommodate the product's connecting wire harness. The buffer liner 2 can form a cavity with the first side wall 111, thereby providing sufficient buffer protection for the product's connecting wire harness.

[0091] Furthermore, since the support section 23 is attached to the bottom wall 113 and the free end of the support section 23 abuts against the first side wall 111, the cavity structure formed between the buffer liner 2 and the first side wall 111 can be relatively stable, thereby providing a limit for the connecting wire harness, which helps to prevent the connecting wire harness from shaking in the limiting area 3, and thus reduces the possible wear marks on the connecting wire harness.

[0092] In some possible implementations, refer to Figure 2 As shown, the limiting segment 22 is parallel to the second sidewall 112 and perpendicular to the supporting segment 23. In this way, the cavity formed between the buffer liner 2 and the first sidewall 111 can be relatively stable, while the limiting area 3 formed between the limiting segment 22 and the second sidewall 112 can better limit the position of the connecting wire harness in a direction perpendicular to the second sidewall 112.

[0093] In some possible implementations, refer to Figure 3 As shown, the box body 1 also includes two third side walls 114. The two third side walls 114 are located at both ends of the bottom wall 113 along the first direction 001, and the folds between the bottom wall 113 and the two third side walls 114 are parallel to each other and perpendicular to the first direction 001.

[0094] The bottom wall 113, the first side wall 111, the second side wall 112, and the two third side walls 114 form a box 1. For example, the first side wall 111 and the second side wall 112 may be located at the two ends of the bottom wall 113 along the second direction 002. The second direction 002 may be parallel to the bottom wall 113 and perpendicular to the first direction 001.

[0095] In this way, one third sidewall 114 can work together with the buffer liner 2 to define the position of the product body in the first direction 001, and the other third sidewall 114 can work together with the product body to define the position of the connecting harness in the first direction 001.

[0096] In some possible implementations, refer to Figure 4 As shown, the packaging box also includes two fastening components 4, which are located at both ends of the bottom wall 113 along the first direction 001. Each fastening component 4 includes a damping plate 41 and two limiting plates 42.

[0097] Combination Figure 3 and Figure 5 As shown, the damping plate 41 is located inside the third sidewall 114 at one end and abuts against the first sidewall 111 and the second sidewall 112 along the second direction 002. The damping plate 41 is connected to the end of the corresponding third sidewall 114 away from the bottom wall 113 along the third direction 003.

[0098] Both limiting plates 42 are located between the corresponding damping plate 41 and the third side wall 114, and are connected to the first side wall 111 and the second side wall 112 respectively.

[0099] The crease between the bottom wall 113 and the third side wall 114 extends along the second direction 002, and the third direction 003 is perpendicular to both the first direction 001 and the second direction 002.

[0100] Therefore, the limiting plate 42, located between the damping plate 41 and the third side wall 114, can limit the damping plate 41 along the first direction 001. Simultaneously, the connection between the damping plate 41 and the third side wall 114 can restrict the limiting plate 42 from rotating around the first direction 001. Furthermore, since the damping plate 41 abuts against the first side wall 111 and the second side wall 112, the friction between the damping plate 41 and the first and second side walls 111 can limit the rotation of the damping plate 41. This ensures sufficient structural stability for the box body 1. Simultaneously, the fastening assembly 4 can assist the corresponding third side wall 114 in providing support, improving the structural stability of the packaging box and achieving good protection for the product.

[0101] In some possible implementations, the size of the damping plate 41 along the second direction 002 can be slightly larger than the distance between the first sidewall 111 and the second sidewall 112, thereby improving the friction between the damping plate 41 and the first sidewall 111 and the second sidewall 112. For example, both ends of the damping plate 41 can extend 2mm to 3mm beyond the space between the first sidewall 111 and the second sidewall 112.

[0102] In some possible implementations, refer to Figure 3 As shown, the box body 1 also includes a cover plate 115 and an extension plate 116. The crease between the cover plate 115 and the second side wall 112 extends along the first direction 001, and the cover plate 115 is opposite to the bottom wall 113. Thus, the cover plate 115, together with the bottom wall 113, the first side wall 111, the second side wall 112, and the two third side walls 113, can form the box body 1, thereby limiting the position of the product in three-dimensional space and achieving full protection for the product.

[0103] The extension plate 116 is located outside the first side wall 111 and is connected to the cover plate 115. The extension plate 116 is provided with insert plates 1161 at both ends along the first direction 001. The insert plates 1161 can be inserted between the limiting plate 42 and the third side wall 114 at the corresponding end.

[0104] For example Figure 4 As shown, the cover plate 115 can rotate along the crease between the cover plate 115 and the second side wall 112, so that the extension plate 116 can be located outside the first side wall 111, and the insert plate 1161 can be inserted between the limiting plate 42 and the third side wall 114 at the corresponding end. In this way, the cover plate 115 can be fastened by the extension plate 116 and the insert plate 1161 thereon.

[0105] It should be noted that the inner side refers to the side facing the inside of box 1, while the outer side is the opposite of the inner side and is the side facing the outside of box 1.

[0106] In some possible implementations, the damping plate 41 has a latching groove 411 on the side facing the bottom wall 113 along the third direction 003. In this way, when it is necessary to unfold the box 1, the damping plate 41 can be easily unfolded by latching the latching groove 411.

[0107] In some possible implementations, refer to Figure 4 At least one third sidewall 114 has a socket 1141 in its middle portion, and the socket 1141 penetrates the third sidewall 114 along the first direction 001. For example, in Figure 4 In this case, a socket 1141 is provided in the middle of one of the third sidewalls 114, but it is also possible that a socket 1141 is provided in the middle of both of the second and third sidewalls 114.

[0108] Therefore, the packaging box can be easily lifted or picked up by inserting a finger into the socket 1141.

[0109] In some possible implementations, when the packaging box also includes two fastening components 4, and the fastening components 4 include damping plates 41, the damping plate 41 at one end is also provided with a clearance hole 412, which is coaxial with the insertion hole 1141. This can prevent the damping plate 41 from blocking the insertion hole 1141.

[0110] In some possible implementations, refer to Figure 4 As shown, in the second direction 002, the size of the limiting plate 42 can be equal to or slightly smaller than half the internal size of the box 1. Therefore, material can be saved while ensuring the supporting and limiting capacity of the limiting plate 42.

[0111] In some possible implementations, the two limiting plates 42 of the same fastening component 4 may each have a relief groove 421 on the side facing each other to avoid blocking the insertion hole 1141.

[0112] On the other hand, this embodiment also provides a packaging component, as referenced Figure 6 As shown, the packaging components include any of the packaging boxes of this utility model.

[0113] The packaging component of this embodiment includes the packaging box of this application and has all the beneficial technical effects of any embodiment of this utility model.

[0114] In some possible implementations, the box body 1 further includes a bottom wall 113. The creases between the bottom wall 113 and the first side wall 111 and the second side wall 112 are all parallel to the first direction 001.

[0115] refer to Figure 12 and combined Figure 9 As shown, the packaging assembly also includes a cushioning base 5. The dimensions of the cushioning base 5 along the first direction 001 and the second direction 002 match the internal dimensions of the box body 1. For example, the dimensions of the cushioning base 5 along the first direction 001 and the second direction 002 can be equal to or slightly smaller than the internal dimensions of the box body 1. Both the first direction 001 and the second direction 002 are parallel to the bottom wall 113, and the first direction 001 and the second direction 002 are perpendicular to each other.

[0116] Furthermore, the cushioning base 5 is located on the side of the cushioning liner 2 opposite to the bottom wall 113. For example... Figure 9 As shown, the support portion 23 can indirectly abut against the bottom wall 113 by abutting against the cushioning pad 5, and the limiting area 3 can be formed by the limiting section 22, the cushioning pad 5, and the second side wall 112. In this way, the product can be cushioned by the cushioning pad 5 in a direction perpendicular to the first direction 001 and the second direction 002.

[0117] In some possible implementations, refer to Figure 7 and Figure 8 and combined Figure 15 As shown, the cushioning pad 5 is formed by folding a one-piece molded sheet through preset creases. The cushioning pad 5 includes a cushioning plate 51, two first support plates 52, and two second support plates 53.

[0118] Among them, reference Figure 7 and combined Figure 9 As shown, the two first support plates 52 and the two second support plates 53 can all be located between the buffer plate 51 and the bottom wall 113, which can provide support for the product along the third direction 003. A cavity can be formed between the buffer pad 5 and the bottom wall 113 to improve the buffering capacity of the buffer pad 5.

[0119] Continue to refer to Figure 7 and Figure 8 As shown, two first support plates 52 are located at both ends of the buffer plate 51 along the first direction 001, and two second support plates 53 are located at both ends of the buffer plate 51 along the second direction 002, which can improve the support stability of the buffer pad 5. Furthermore, the structure of the buffer pad 5 is relatively simple and easy to manufacture, thus significantly reducing labor costs and manufacturing costs.

[0120] In some possible implementations, the second support plate 53 is provided with first reinforcing plates 531 at both ends along the first direction 001, and the first reinforcing plates 531 are located inside the corresponding second support plate 53. The first reinforcing plates 531 can buffer the stability of the base pad 5 and strengthen the support strength of the buffer base pad 5 in the vertical direction.

[0121] In one example, refer to Figure 7 and Figure 15 As shown, the crease between the cushioning plate 51 and at least one first support plate 52 has a clearance hole 54. Thus, the cushioning pad 5 can be easily removed from the packaging box by pressing the clearance hole 54 with a finger.

[0122] In one example, refer to Figure 12 As shown, the portion of the clearance groove 54 located on the first support plate 52 can match the socket 1141. For example, the portion of the clearance groove 54 located on the first support plate 52 can be opposite to the socket 1141. Thus, the buffer pad 5 can be prevented from blocking the socket 1141.

[0123] In some possible implementations, the box body 1 further includes a bottom wall 113. The creases between the bottom wall 113 and the first side wall 111 and the second side wall 112 are all parallel to the first direction 001.

[0124] Furthermore, refer to Figure 6 As shown, the inner cushioning liner 2 is located at the first end of the box body 1 along the first direction 001. The packaging assembly also includes a cushioning side liner 6. The cushioning side liner 6 is located at the second end of the inner cushioning liner 2 along the first direction 001. The cushioning side liner 6 can improve the protective support capability of the packaging assembly for the product along the first direction 001 and improve the structural stability under extreme transportation conditions.

[0125] In some possible implementations, refer to Figure 6 and combined Figure 12 and Figure 13 As shown, the inner cushioning liner 2 and the side cushioning liner 6 can both be located on the upper side of the bottom cushioning pad 5.

[0126] In some possible implementations, refer to Figure 16 and combined Figure 10 and Figure 11 As shown, the buffer side liner 6 is formed by folding a one-piece molded sheet through preset creases. The buffer side liner 6 includes a side limiting plate 61 and two side support plates 62.

[0127] refer to Figure 10 and combined Figure 11 As shown, the side limiting plate 61 is located at the first end of the two side support plates 62 along the first direction 001, and is used to abut against the product to support the product along the first direction 001. The crease between the side limiting plate 61 and the support plates of the two side support plates 62 extends along the second direction 002.

[0128] Continue to refer to Figure 10 As shown, the side support plate 62 is provided with a third support plate 621 at both ends along the second direction 002, and the third support plate 621 is located between the two side support plates 62.

[0129] The first direction 001 and the second direction 002 are both parallel to the bottom wall 113, and the first direction 001 and the second direction 002 are perpendicular to each other.

[0130] Therefore, a cavity can be formed inside the buffer side liner 6, and the side limiting plate 61 can achieve good cushioning of the product along the first direction 001. At the same time, the structure of the buffer side liner 6 is relatively simple and easy to manufacture, thus significantly reducing labor costs and manufacturing costs.

[0131] In some possible implementations, the side limiting plate 61 may also be provided with second reinforcing plates 611 at both ends along the second direction 002, with the second reinforcing plates 611 located inside the third support plate 621 at the corresponding end. The second reinforcing plates 611 and the two third support plates 621 at the corresponding end may overlap along the second direction 002. This can improve the structural stability of the buffer side liner 6.
